Abstract :
A new method to calculate the absorbed power density in closed microwave systems is presented. The method, which is based on the use of a dual variational principle and three-dimensional finite elements, extracts more information from the field solution than a previously published method. The calculation of the total incident and reflected power in a microwave cavity is discussed.
